1.	The warranty of this equipment is to be free from defects in material and workmanship for a period of one year from the purchase date. Any units or parts which prove defective during the warranty period will be replaced at the manufacturers’ option when returned to the manufacturer, transportation prepaid.
2.	Motor Warranty is warranted by the motor manufacturer for a period of one year. Should motors furnished prove defective during this period, they should be returned to the nearest authorized motor service station.

2. 	PRODUCTS

2.1	GENERAL

A.  Base fan performance at standard conditions (density 0.075 Lb. /ft3).
B.	Fans selected shall be capable of accommodating static pressure and flow variations of +/-15% of scheduled values.
C.	Each fan shall be belt drive in AMCA arrangements 1 [9, 10] according to drawings. 
D.	Fans are to be equipped with lifting lugs.
E.	After fabrication, all carbon steel components shall be cleaned and chemically treated by a phosphatizing process to insure proper removal of grease, oil, scale, etc. Fan shall then be coated with a minimum of 2-4 mils of Permatector (Polyester Urethane), electrostatically applied and baked. Finish color shall be gray, RAL-7023. Coating must exceed 1,000-hour salt spray under ASTM B117 test method.

D.	Fan shaft bearings shall be Air Handling Quality, bearings shall be heavy-duty grease lubricated, self-aligning or roller pillow block type.  
E.	Air Handling Quality bearings to be designed with low swivel torque to allow the outer race of the bearing to pivot or swivel within the cast pillow block. Bearings shall be 100% tested for noise and vibration by the manufacturer. Bearings shall be 100% tested to insure the inner race diameter is within tolerance to prevent vibration.
F.	Bearings shall be selected for a basic rating fatigue life (L-10) of 40,000 hours at maximum operating speed for each pressure class {Average Life or (L-50) of 200,000 hours}.
